I remember reading somewhere that schizophrenics drop an average of 1-2 standard deviations (down to an average of 70/80ish) after having schizophrenia for a while.
I have also noticed this in my mother, who also has schizophrenia. She has trouble grasping basic concepts when they are explained to her, and she also says that she doesn’t feel as smart as how she used to feel. The difference is also big enough that I’ve had other people mention it to me in private.
What’s the reason for this? Is there any explanation?
Also the numbers I mentioned about 70/80iq average are just from my memory of reading an article, I didn’t verify the exact number.

IQ tests are flawed, they don’t truly show how intelligent a person is, rather how well prepared they are to take said test. I can imagine a schizophrenic person would be at a disadvantage taking an iq test.
If a person has schizophrenia their thought patterns will be disturbed to some degree, and this will mean that, while their potential IQ may be unchanged, the results in tests and in practical situations (their day to day functioning and decision making) will be impaired.
Imagine having to do a test in a room with loud, annoying music playing. Or when really tired, or when you have a serious problem that you can’t stop thinking about. That’s the kind of effect disturbed thought patterns could have
